Modular reconfigurable edge computing node

ABSTRACT

A reconfigurable edge computing node of a complex system is provided, the edge computing node including a core module executing selectable core software, and selectable input module(s) and/or output module(s) which can be installed in corresponding input/output ports, wherein each of the input module(s) or output module(s) provides a conduit for moving data to or from the complex system, with selections being chosen from catalogs of available input modules, available output modules, and available core software. The edge computing node provides reconfiguration upon attachment of any input or output module(s), or upon installation of any core software, automatically reconfiguring the edge computing node to enable communication between the core module and the input module(s) and output module(s) using compatible protocols. Reconfiguration of the edge computing node has been previously tested for each allowable combination of available selections of the input and output module(s) to satisfy a certification requirement.

The present disclosure relates to system data processing needs for diverse components and subsystems of a complex system, and more particularly to a modular reconfigurable edge computing node to enable data processing needs for diverse components and subsystems of a complex system.

BACKGROUND

In a complex system having multiple components and subsystems, there is a need to monitor each of these components and subsystems. As the components and subsystems evolve over time, the local monitoring system for monitoring these evolving components and subsystems will require updates coinciding with evolving performance and functional demands.

Furthermore, testing each of the different local monitoring systems can be time consuming and arduous when the complex system must comply with particular standards, such as those due to regulations enacted by an overseeing governance. For example, every component of an aircraft must comply with strict certification requirements. The certification process can be quite lengthy. Each local monitoring system must undergo a certification process, including each newly updated version, causing repetition of application of the certification process. Each instance of undergoing a certification process for a component or subsystem of the aircraft drives up cost and can cause delays to deployment of sales of the component, subsystem, and/or aircraft.

Conventional methods and systems have generally been considered satisfactory for their intended purposes. However, there is still a need in the art for an improved system and method for monitoring of components or subsystems of a complex system that reduce the need for repeating processes for compliance with regulations. The present disclosure provides a solution for this need.

The machine typically includes memory storage configured to provide output from execution of the computer algorithm or program.

Reference will now be made to the drawings, in which like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, an illustrative view of an embodiment of a complex system in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 100. Other embodiments and/or aspects of this disclosure are shown in FIGS. 2-5. Referring to FIG. 1, a schematic diagram of an example of complex system 100 is shown, wherein complex system 100 includes a variety of components and/or subs-systems, which are referred to generally as components 104. Components 104 of complex system 100 can be monitored, such as for prognostics, health, maintenance, diagnostics, reliability, efficiency, security, etc. Components 104 can monitor themselves, e.g., for health or status, and output monitored data about themselves or can be monitored by sensors, referenced generally as sensors 108, that output monitor data about the components 104 monitored by the sensors 106. Furthermore, complex system 100 and all of its components 104 and sensors 106 are regulated and required to be tested and certified as satisfying test criteria. The test criteria can be determined by a governing body, such as a regulatory agency, that certifies each component 104 and sensor 106 in complex system 100.

In the example shown, the complex system 100 is an aircraft and the components 104 include a motor controller 104 a, a cabin air compressor 104 b, and landing gear 104 c associated with moving elements, such as motors and actuators. Other examples of components in the context of an aircraft include braking systems, generators, pitot probes, etc. Furthermore, the aircraft can be a military grade or commercial grade aircraft that has heightened certification requirements governed by a government agency. The disclosure is not limited to a particular complex system or components. Other complex systems that are monitored and highly tested at the component level, e.g., for certification by a governing body, are also contemplated.

Edge computing nodes, referenced generally as edge computing nodes (labeled ECN) 102, are provided that acquire monitor data about components 104, such as via communication links 114 or wirelessly during a data acquisition phase 120. Edge computing nodes 102 acquire monitor data from components 104 or sensors 106. In the example shown, component 104 a can include an embedded processor that provides monitor data via communication link 114 to edge computing node 102 a, wireless sensors 106 a monitoring air compressor 104 b can include an embedded processor that provides monitor data wirelessly to edge computing node 102 b, and sensors 106 b monitoring component 106 c can each include an embedded processor that provides monitor data via communication link 114 to edge computing node 102 c.

Edge computing nodes 102 are configured to acquire the monitor data as received using a specific protocol, perform signal processing and feature extraction on the monitor data and/or localized data analysis, and provide the results as supplemental data wirelessly and/or via a backbone communication link 116 to an aircraft communication hub 110 that has a processor for processing the monitor data and/or transmitting the monitor data out of complex system 100 per whatever protocol is needed.

Communication protocol (also referred to as protocol) refers to a set of formats and rules, such as for governing syntax, semantics, and timing of data communication. A protocol can conform to a standard. Some examples of protocols include wireless access protocols (WAP), IEEE standard 802.11, Bluetooth™, Zigbee™, Ethernet, File Transfer Protocol, Hypertext Transport Protocol (HTTP), Cellular 4G, SATCOM, etc. The term “protocol” as used with respect to data communication, is meant to encompass format, syntax, semantics, standards, etc.

Aircraft communication hub 110 can, for example connect to a main data bus 118 or Wi-Fi system of the aircraft for communicating with components 104, have a user interface for exchanging information with pilots, and/or have wireless communication interfaces for communicating with devices that are external to the aircraft, such as control towers, processors at the airport, etc.

Each edge computing node 102 is a modular, reconfigurable device that starts with a base infrastructure that is modified by selecting from a catalog for each module. All possible reconfigurations of the edge computing node are tested, meaning each allowable combination of available selections from the catalog of each module is tested, meaning for achieving any required certification. Accordingly, any reconfiguration of edge computing node 102 is already pre-tested and certified.

The catalogs can be updated as technologies and requirements evolve, such as during evolution of aircraft design, data acquisition and communication technologies, security requirements, and data-driven applications. The catalogs can include selections that would be used by different sub-systems of the aircraft. Accordingly, when reconfiguring an edge computing node 102, the engineers can select proven, protocol-compatible modules from a catalog. Since the combination of selections from the catalog used to reconfigure the edge computing node have already been pre-tested and certified, no further testing is necessary. When a required modular edge computing node is not available in any of the catalogs, a new modular edge computing node can be designed, tested and certified independently, and added to the catalog for subsequent use. In this way, an ever-evolving edge computing node provides an established base of functionality and structure for enhancement by new modular components without the need to design, develop, or certify the full set of functionality.

With reference to FIG. 2, a block diagram of an example of an edge computing node 102 as reconfigured is shown in greater detail. Edge computing node 102 is reconfigurable, as it is capable of being reconfigured into another configuration. Edge computing node 102 includes a core module 208, one or more input modules 204, and one or more output modules 206. In one or more embodiments, core module 208 includes a single-core central processing unit (CPU). In one or more embodiments, core module 208 includes a multi-core CPU, without limitation to a specific number of cores. In the example shown, core module 208 includes a CPU having cores 209 a, 209 b, 209 c, and 209 d.

Core module 208 includes an input port 212 in which a corresponding input module 204 is installed. Each input port 212 provides a hardware (HW) interface that provides a physical interface between the core module 208 and a corresponding input module 204. Software selected for installation on core module 208 includes a software input interface for interfacing between data received from the input module(s) 204 that were selected and installed in input ports 212 and application software selected and installed on core module 208. The number of input ports 212 can be fixed (meaning not configurable), however every input port 212 does not need to be used. In the example shown, core module 208 has three input ports 212, only two of which are used by an input module 206. Each input port 212 provides the hardware portion of a corresponding input interface.

Core module 208 further includes an output port 222 in which a corresponding output module 206 is installed. Each output port 222 provides a hardware (HW) interface that provides a physical interface between the core module 208 and a corresponding output module 206. The software selected for installation on core module 208 further includes a software output interface for interfacing between the application software selected and installed on core module 208 and data transmitted to the output module(s) 206 that were selected and installed in output ports 222. The number of output ports 222 can be fixed (meaning not configurable), however every output port 222 does not need to be used. In the example shown, core module 208 has three output ports 222, only two of which are used by an output module 206. Each output port 222 provides the hardware portion of a corresponding output interface.

In one or more embodiments, the hardware of core module 208 is not configurable. This means that input ports 212 (including the hardware portion of input interfaces), and output ports 222 (including the hardware portion of output interfaces) are preconfigured.

Core module 208 is configurable by selection and configuration of software from a catalog of core software. The software can control coordination of movement of data received via input port(s) 212 to the output port(s) 222. The software can further be configured to include one or more application software (also referred to as apps) to process the data received via input port(s) 212 before moving the data to the output port(s) 222. The apps can each have a particular purpose for processing the data. The software selected from the catalog of core software can be input for installation on core module 208 via a communication bus of core module 208 and one or more of input ports 212. Core module 208, based on its configuration with the software selected, uses a particular protocol. In order for core module 208 to process or move the data from the input port(s) 212 to the output port(s) 222, the data must be configured using this particular data protocol. Accordingly, the software selected and installed on core module 208 can be configured to perform conversions from a protocol used by the input module(s) to the protocol used by core module 208.

In one or more embodiments, the software can include an operating system (OS). The OS can be, for example, a real time OS (RTOS) or a variant that provides task scheduling and file system support. The catalog of core software can include a selection of different OSs. For example, the OS selections can be application-specific, since one OS selection may work better with applications having a lower level of data access layer usage, whereas a different OS selection may work better with applications having a higher level of data access layer usage. The OS can further facilitate communication with sensors 106, components 104, other edge computing nodes 102, and/or aircraft communication hub 110. The OS can be designed with cybersecurity features (e.g., certificate management, encryption, etc.). Some non-limiting examples of cybersecurity features that could be resident on the edge computing node 102 include Trusted Platform Module (TPM), Enrollment over Secured Transport (EST), Extensible Authentication Protocol Transport Layer Security (EAP-TLS).

In one or more embodiments, the applications executed by core module 208 can process the data received from input module(s) 204 for monitoring health of the input module(s) 204 and validating data received by the input module(s) 204.

In one or more embodiments, the data processed by the core module 208 and moved to the output module(s) 206 via the output interface(s) facilitates health monitoring of the output module(s) 206.

Core module 208 can further include additional elements 250, such as a power source, electro-magnetic interference (EMI) protection, and signal conditioning circuitry for the input ports 212 and/or output ports 222. In addition, core module 208 can further be provided with an enclosure 260 that can be hardened and/or provide additional thermal, EMI, vibration protection, and/or shock protection, such as for use in harsh environments.

Each of input module(s) 204 is selected from a catalog of different types of available input modules. Input module 204 is configured to physically connect with input port 212 for enabling data communication with the software installed on core module 208. Each input module 204 is a hardware device that provides a physical conduit for data from a data source of the complex system 100 to the core module 208 via its corresponding input port 212 in which the input module 204 is installed.

The individual input module(s) 204 can include an embedded processor 210, such as a microprocessor, field-programmable gate array (FPGA), etc. that includes conversion software configured to convert data received by the input module 204 into a protocol that is usable by core module 208, and namely by the applications with which core module 208 is configured for processing data received from the input module 204.

In one or more embodiments, each input module 204 is provided with a pre-selected embedded processor 210 that is configured specifically for the input module 204.

In one or more embodiments, the embedded processor 210 can be selected from a catalog of different available input embedded processors in order to achieve a desired configuration of input module 204.

Each of output module(s) 206 is selected from a catalog of different types of available output modules. Output module 206 is configured to physically connect with output port 222 for enabling data communication with the software installed on core module 208. Each output module 206 is a hardware device that provides a physical conduit for data from core module 208 to a computing device included in or exterior to the complex system 100 via the output port 222 in which the output module 206 is installed.

The individual output module(s) 206 can include an embedded processor 210, such as a microprocessor, FPGA, etc. that includes conversion software configured to convert data received by the output module 206 from core module 208, and namely by the applications with which core module 208 is configured for processing data sent to the output module 206. The embedded processor 210 can convert data received from core module 208 into a format that is compatible with the computing device to which it is coupled.

In one or more embodiments, each output module 206 is provided with a pre-selected embedded processor 210 that is configured specifically for the output module 206. In one or more embodiments, the embedded processor 210 can be selected from a catalog of different available input embedded processors in order to achieve a desired configuration of output module 206.

Testing the combination of selections from the catalogs available to use to reconfigure the edge computing node 102, e.g., for certification by a regulatory board, can further include testing each allowable combination, including each allowable combination with a selection from the catalog of available input embedded processors and/or the catalog of available output embedded processors.

The testing of each allowable combination of available selections from the available catalogs (e.g., the catalog of available input modules, the catalog of available output modules, the catalog of available core software, and the catalog of embedded software modules for the input and output modules) includes validating each allowable combination of available selections, detecting any configuration violation that resulted in a failure to validate, reverting edge computing node 102 to a default “do no harm” state upon detection of a configuration violation, and outputting notification of a configuration violation.

Validating each allowable combination of available selections includes, for each allowable combination, individually validating the configuration of each input module 204 (which includes its embedded software module 210, if any), each output module 206 (which includes its embedded software module 210, if any), and the core module 208, as well as validating the configuration of the overall edge computing node 102 while in its reconfigured state (with input and output modules 204 and 206, respectively, installed, including before and after the core module performs any automatic reconfiguration). Validation includes matching a configuration of each installed module (meaning each input module 204 and output module 206) upon identifying itself to the core module 208 based on an expectation of the core module 208, and establishing a brief communication exchange with the installed module. For example, an input module 204 might have a programmable data file with configuration parameters. The core module 208 matches receives these configuration parameters upon installation of the input module 204 and matches these configuration parameters to an entry in a corresponding data table stored in the core module 208. Core module 208 further establishes the brief communication exchange with the input module 204. Failure to establish this communication or to find an entry in its data table that matches the configuration parameters causes the validation to fail.

The edge computing node 102 reverts to the default “do no harm” state when validation fails by not accepting a connection of an input module 204 or output module 206 that could not be validated. In effect, the core module 208 maintains prior operation (such as with other previously validated input modules 204 and/or output nodules 206) and treats the input module 204 or output nodule 206 that failed validation to be in an “off” or “inert” state. This ensures that continued operations will only reflect validated configurations.

Notification of a configuration violation is performed by outputting a flag via one of the previously validated output modules 206. For example, a discrete value (e.g., a binary value of 0 or 1) may be triggered, or a data tag on a communication bus may be set to a “validated” or “failed” status.

Once edge computing node 102 is reconfigured by installing the selected software of core module 208 and by installing each of the selected input module(s) 204 and output module(s) 206 in the corresponding input port(s) 212 and output port(s) 222, respectively, the selected software installed and executed by core module 208 can detect installation of input module(s) 204 and output module(s) 206. Edge computing node 102 can be dynamically configured once installation of the input module(s) 204 and/or output module(s) 206 is detected. Methods for dynamically configuring edge computing node 102 can include a range of methods from simple pin programming to more sophisticated internet protocol (IP) certificate-based configurations by core module 208 of input or output modules 204 and 206, respectively, using configuration data. The configuration data can be in the form of parameter data item files (PDIFs). Range and Compatibility of settings of the configuration data can be verified at design time

This detection can trigger core module 208 to perform automatic reconfiguration of the edge computing node 102 to correspond to the input module(s) 204 and output module(s) 206 that have been attached to the core module 208.

In one or more embodiments, automatic reconfiguration can include the core module 108, as configured with the selected software, determining a choice of protocols from the limited prescribed set used by the input data provided by the one or more input modules and/or provided to the one or more output modules. The determination of protocols can be performed, for example, using a handshaking between core module 208 (using the selected software) and the input module(s) 204 and/or output module(s) 206 as selected and installed.

Based on this determination of protocol(s) used, the core module 208 can be configured to automatically configure itself, e.g., its software input interface, to use a protocol that is compatible with the determined protocol for enabling communication between core module 208 and the input module(s) 204 and/or the output module(s) 206. This encompasses core module 208 configuring itself to use different protocols for communicating with input module(s) 204 versus output module(s) 206.

In one or more embodiments, based on this determination of protocol(s) used, the core module 208 can be configured to automatically convert input data received from input module(s) 204 or convert the data to be output to output module(s) 206 to use a protocol that is compatible with a protocol used by core module 208 for enabling communication between core module 208 and the input modules 204 and/or the output module(s) 206.

In one or more embodiments, based on this determination of protocol(s) used, core module 208 can configure a processing device of the input modules (204) or of the output modules (206) to select a protocol to be used for enabling communication between core module 208 and the input modules 204 and/or the output module(s) 206. In one or more embodiments, based on this determination of protocol(s) used, core module 208 can configure a processing device of the input modules (204) or of the output modules (206) to convert the input data provided by the one or more input modules or provided to the one or more output modules to use a protocol that is compatible with the core module for enabling communication between the core module and the one or more input modules and/or the one or more output modules. In one or more embodiments, automatic reconfiguration of edge computing node 102 can include optimizing performance of edge computing node 102 based on the configuration of core module 208 (meaning the software selected and installed on core module 208), the configuration of the input module(s) 204 (meaning the input module(s) 204 that were selected and installed), and the configuration of the output module(s) 206 (meaning the output module(s) 206 that were selected and installed). This performance optimization can, for example, include selection of particular software protocols used by core module 208 and the embedded processors 210 of the input modules 204 and the output modules 206, if so equipped, to exchange data between the core module 208 and input and output modules 204 and 206, respectively; and/or utilization of specific processing cores 209, if so equipped, for particular functions.

In one or more embodiments, automatic reconfiguration of edge computing node 102 can include identifying the one or more input module(s) 204, the input embedded processors 210 (if any), the one or more output module(s) 206, and/or the output embedded processors 210 (if any). Furthermore, automatic reconfiguration of edge computing node 102 can include configuring the input embedded processor 210 and/or the output embedded processor 210 based on the identification. In one or more embodiments, core module 208 can configure its own installed software to accommodate the protocol used by the input module(s) 204 and/or output module(s) 206 based on their identification.

In one or more embodiments, automatic reconfiguration of edge computing node 102 can include, only once identified, using methods for dynamic authenticating and/or authorizing input module(s) 204 and/or the output module(s) including their embedded processors 210 (if any). The methods for dynamic authentication and/or authorization can range from simple pin programming to more sophisticated internet protocol (IP) certificate-based authentication and/or authorization for continued communication between core module 208 and input or output modules 204 and 206 respectively. Authentication and authorization ensure that fraudulent or valid but as-yet-incomplete input modules 204, output modules 206, and core module 208 cannot interfere with the proper operation of the edge configuration node 102.
